Interpretation: The option in which carbohydrate are not present needs to be determined.
Concept Introduction:
Carbohydrate- Carbohydrates are the naturally occurring organic compound. It consists of carbon, hydrogen, and oxygen. There are

Answer to Problem 5STP
Correct answer: Option (D) dipeptide.
Explanation of Solution
Reason for correct option:
Dipeptide is the type of linkage present between two amino acids to form the protein. The term peptide is connected with the protein. This linkage provides the strength to the structure of proteins.
Reasons for incorrect options:
Option (A) starch is classified under the carbohydrate, hence it is incorrect option.
Option (B) cellulose is the type of carbohydrate. Hence it consider as incorrect option.
Option (C) glycogen is the type of carbohydrate, hence it is incorrect option.
